Y ATTACHMENT Eon- PLUMBING FIXTURES.

vApplication mea January 26,1924. serial No. 638,748.

To all whom t 'in/ary concer/ft:

Be it known that I, CHARLES HERMANN WAEorI'rEma citizen ofV the UnitedStates, residing in New York, county of New York,

and State of New York, have invented cerfixture, which will provide4means for controlling the rate of'ldischarge and the heighty of waterwithin the fixture while effectually preventing air suction and vorticesprimarily the causev of the discharge noises particularly objectionablein dwellings.

It is my particular object to provide an attachment forv the verflowsVof'bath tubs permitting the user to control theV overflow leveltherenand enjoy the'benets ofsuoh water level as may best suit hisconvenience and physique while assuring thatthejoutowing liquiddischarge will be silent and of minimum quantity Vfor ythe maintenanceof solutions of constant density when bathing preparations are employed.

Certain other improvements accomplished V by my invention will beapparent from the following description. of one embodiment thereof. d Y

Like numerals have been employed to indicate like parts throughout theseveral views. In the drawings- Figure 1 is a front elevation of a preferred embodiment of my invention,

Figure 2 is a cross section of Figure 1, taken upon line 2-2,

Figure 3 illustrates an application of my 'f invention to a standardbath tub and shows the device of Figure 1 crossesectioned in verticalplane as upon 1ine.3-3.

VReferring particularly to Figures l and gular in outline, the edge 14Vsupplying a Weir for the discharging Vwater as will be described. Sides9 and the end 10 are preferably provided at their edges with an insertof packing material l5, for water-tight abutment against the interiorsurface ofthe bathtub in such manner that this surface forms lthe fourthside of the box as shown in Figurev 3. d Y

The interior surfaces of bath tubs are usually of porcelain likesmoothness andofk extreme hardness, and drilling the fixture withoutchipping this surface in a destructive manner is practically impossible.Engagement of the other fittings of the tub, such as faucets 20, toretainv an attachment involves `ungainly. structures not universallyadaptable to all installations.

Attachment of mydevice is secured withoutthe foregoing difficulties bythe employment ofr vacuum cups 22, preferably of rubber. bar 24bysuchmeans as the studs 26. This cross bar 24 is provided with openings slid-Cups 22 are secured to a cross eenk ably engaging the studs 28 which areatf tached to the back'7 of box member 5.v For adjustment of therelation between the vacuu-m cups and the member 5, and tocompresspacking 15 fory the formation of a water-tight joint with the tubsurface, a thumb screw 30 is threaded into the bar 24 and bears uponback 7.

In use the cups 22 are moistened and then pressed against the innersurface 32 excluding the air from the spaces 34. The pressure of thesurrounding atmosphere then holds the cups to the tub surface. Thus toapply the device to a bath tub the user merely places it over the wasteopening 35 of the bath tub andpresses the cross bar 24 causing thesuction cups 22 to grip the tub surface.` yHe then turns thumbscrew 30until it bears on back 7 and thus compressesy the packing 15. The deviceis now in working position.v It will be understood that the tub may beengaged at any height with reference to the waste opening 35 and thatthe water level in the tub will be controlled by the height of edge 14,as all discharge to the opening 35 must be over this edge. Edge 14therefore forms a weir for the discharg ing water spreading it into athin sheet entering they opening at right anglesto its Manifestly withmy invention applied a Cil much higher Water level may be maintained inthe bath tub and this level may be as much higher than the normaloverflow level as one desires. p

Many changes and modiications are possible in the structure and in theparts of my invention with the accomplishment of beneicial results, allWithin the spirit of my invention and Within the scope of the appendedclaims as Will be understood by those skilled in the art. lVhile myinvention has been particularly described as suited to bath tubs, itwill be clear that it is equally suited to other plumbing fixtures andwhile it has been shown as applied to the overi'ow Waste opening, itwill be apparent that it can be equally Well applied to other openingslWith the accomplishment of improved results.

VThat I claim is: Y

l. In a device for adjusting overflow level in a bath tub, a box membercovering the bath tub overflow opening and adjustable means forretaining' said member at the desired height respective thereto, saidmeans including suction cups attaching members engaging the interiorsurface of the tub.

2. In an overiow attachment for bath tubs having waste openings insubstantially vertical plane, a box member having an open side and end,adjustable suction means for securing said member over the Waste openingwith its open side in registry therewith and with its open end upward.

3. An adjustable overovv attachment for plumbing fixtures comprising athree-sided member having an open end, the edges of said member beingprovided with llexible means conforming to the interior fixture surfacesurrounding a Waste opening, the open end of said attachment forming aninner overflow orifice, and suction cups secured to one side of the saidattachment being adapted to position the attachment at any desiredheight.

el. In an 'overflow attachment tor bath tubs a Waste pipe extensioncomprising a hollow member having an open side and a Waste inlet gasket,means secured to the side edges of said member, suction cups engagingthe tub surface, a cross bar connecting said cups and means engagingsaid member and cross bar to support the aforesaid mein* ber with theWaste inlet uppermost and with its open side against the tub surfaceover the Waste pipe opening.

5. In a discharge attachmenti'or bath tubs a member of substantiallyrectangular cross section having a semicircular closed end, asubstantially straight open end, three closed sides and an open side,suction means for engaging the tub surfaceJ adjustable means forsimultaneously engaging the suction means and one of the closed sides ofsaid member to secure said member over the bath tub discharge openingfor the control thereof.

In testimony whereof I have allixed my signature to this specification.

CHARLES HERMANN WAECHTER.
